Hi Olaf,
Sorry it took me a while to have a look at this problem.
Unfortunately, for the IBM platforms that I have access to,
they are still stuck at version 6.0.0.3 of the compiler set.
So I just see the internal compiler error with these example
codes, as before. I have asked the support group to upgrade
the compiler version for me.
Meanwhile, it looks to me from reading the compiler error
messages that you reported that perhaps the compiler is just
confused about the template matching when the prototype is
an Array reference and the given type is an Array. It is possible
that making the prototype an Array const reference will resolve
this problem. You could try, for example, changing line 146
of <blitz/array/stencil-et.h> to use a const reference, and see if
this resolves the error coming from the use of Laplacian2D in
the stencil2.cpp example code.
I will look into this as soon as I have the newer compiler installed
and will attempt to provide a more complete resolution then.
Thanks, Julian C.
